Airbag control unit with part number 9673657980

What does the airbag control unit 9673657980 do?

The airbag control unit 9673657980 coordinates the restraint system (SRS) of Citroën. It evaluates the crash sensors, decides within milliseconds in a crash which airbags and seatbelt pretensioners are triggered, and monitors the system continuously.

The unit reports faults via the airbag warning light in the instrument cluster. After a crash, it stores crash data and locks itself.

Why does the control unit 9673657980 fail?

Crash data stored after an accident is the most common cause, even if no airbag has triggered. A normal diagnostic tool is not affected by this, because it cannot delete the data. Other causes are aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes.

Which cause applies in the specific case must be shown by the fault memory. A plug or a cable can also trigger messages that point to the unit.

Voltage spikes occur, for example, with a weak battery or a jump start.

How can you tell that the 9673657980 is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently, and an error message appears in the instrument cluster. In addition, there is no connection to the diagnostic tool, or the fault memory cannot be cleared.

If the restraint system is disrupted, airbags and seatbelt pretensioners may not trigger in an emergency. The light indicates the finding, so a prompt check is appropriate.
